Tachyon Original Standard Front.png

Have you ever taken the time to wonder who is responsible for most of the innovations in our world? Who made it possible to get your car’s gas mileage over 60 miles to the gallon by changing the way the world uses fuel? Who finally found the key that would lead to the cure for cancer? Whose unrelenting expertise resulted in the first mission to send humans to Mars? You may be surprised to find out that there is just one answer to these questions: Dr. Meredith Stinson.

You may have heard that name before. Most of her accomplishments have gone largely unheralded in the public sphere; however, Dr. Stinson has had a hand in research across the entire scientific spectrum. She’s dabbled in everything from military technology to cheaper methods of ore processing, from learning patterns in rodents to the dietary habits of school children, and from more environmentally friendly waste management to developing a system for indefinite water renewal. That said, for all of the fields she’s made an influence in, her greatest achievements have been in the field of particle physics.

Dr. Meredith Stinson was the driving force behind the creation of the Particle Yield Enhancing Wavelength at the Eaken-Rubendall Laboratory, a technology meant to revolutionize travel and transportation. Its purpose would be to use light to transport objects. In theory, it would transport objects at the speed of light without the normal dangers of high-speed travel. It was this device that would finally bring her into the public eye, but not for any reason which Dr. Stinson could have anticipated. While calibrating the device, a safety mechanism failed, sealing Dr. Stinson within the testing chamber as the machine began to boot up. Springing to action, her team struggled to free her from the chamber, but they were unable to open the doors before the device finished its startup sequence. Dr. Stinson was thrown to the floor as the chamber was flooded with tachyons, but to everyone’s surprise, she emerged apparently unscathed.

Shaken but returning to work, she began to notice an unusual increase in her efficiency. Tasks that would have taken hours were done in half the time, and she found herself unconsciously picking up speed as she moved about the lab. Steadying herself, she carefully drew a blood sample from herself for further examination. To her surprise, she discovered that the cells within her body had been accelerated. Securing a wind tunnel within the facility for herself, she began to test the extent of her changes and found that she could move at superhuman speed.

News of her findings quickly spread, resulting in the government recruiting her for a new initiative. Dr. Stinson was offered nigh-unlimited research funds in exchange for her services. If you still have yet to figure out why her name sounds so familiar to you, then we’ll finally cut to the chase: Dr. Meredith Stinson is most commonly known as Tachyon, the quickest woman on Earth, and the third member of the Freedom Five.

Super Scientific Tachyon

Variant: Originally released as a promotion for the release of the Sentinels of the Multiverse: Video Game

Freedom Five: Tachyon

Variant: Originally revealed during the OblivAeon Kickstarter as the $1 Million stretch reward.

When Dr. Meredith Stinson originally joined the Freedom Four, she did so to help fund research at her lab. She was initially much more interested in science and research. She would not have hypothesized that time with a team of heroes would change her as much as it did.

Now, Tachyon is even more well known for her heroism than she is for her brilliant mind. No matter - she still gets plenty of time in the lab, and her role with the Freedom Five has given her unique opportunities to study all manner of seemingly impossible phenomena throughout the Multiverse.

Variant: Originally revealed during Shattered Timelines Kickstarter as the $40k stretch reward.

Alternate Future from main timeline; Iron Legacy Variant

After Legacy's fall, and the rise of the Iron Legacy global domain, Tachyon went deep into hiding. With her speed and smarts, she was able to avoid Legacy and his Iron Guard, but it took years before she was ready to rebuild a team.

Dr. Stinson scoured the globe for her former teammates and found those who had surived. Most were worse for wear, but, with the addition of an old foe in the hollowed-out shell of an experimental Bunker suit, and a mechanical golem that believes it is actually the long-dead Unity, a new team was formed. Will they be strong enough to withstand the great challenge they face? Only time will tell…

Sentinel Tactics: Tachyon

Legacyicon.png Legacy Wants to Remind You! This following information is from Sentinel Tactics, one of two branching alternate timelines after the OblivAeon Event!

Dr. Stinson and former-Lt. Vance worked together to build a new Bunker suit - this one no longer benefitting from military R&D and ordnance, but still something that would allow Tyler Vance to bring his tactical genius to bear on the battlefield. And, of course, it would also provide an impressive amount of firepower. Though still a massive metal suit, this new Bunker was smaller and more efficient than previous versions and could be launched considerable distances from Freedom Tower.

Incapacitated Images

Variant Pack New Artwork

The All Heroes Variant Pack released with OblivAeon contains new artwork for the heroes and their variant cards.

Tachyon Hero Deck

Rule 15

Cards that previously required you to take damage to keep them in play (Such as Ra Solar Flare or Tachyon Pushing the Limits) are now clarified to be destroyed if this damage is not taken. Cards officially reprinted are:

  • Fanatic: Chastise
  • Fanatic: Embolden
  • Tachyon: Pushing the Limits
  • Ra: Solar Flare.

The text of these all these cards now reads "If [He/She/They] take no damage this way, destroy this card"

This Ruling is not limited to these cards, simply these were the ones that were reprinted. Any other card that requires its user to take damage to keep it in play is affected as well

(Known as Rule 15 because it was the 15'th point on a list of rules questions posted on the forums that were posed to Christopher during KantCon)

Fireside Chats

  • If The Super Scientific Tachyon chooses a deck with one card in it, the card is discarded.
  • The Super Scientific Tachyon gets to decide the order in which the two cards she reveals are played or discarded.
  • When a card enters play, the following order of things occurs.
    • Ongoing effects on the card become applicable.
    • Cards that react to other cards entering play now act.
    • One-time effects on the card happen.
    • ...Another example: Supercooled Trisolvent Vat and Synaptic Interruption. Suppose damage dealt to Tachyon is increased by 2. When Tachyon plays Synaptic Interruption, the Vat does 3 cold damage to Tachyon. Tachyon may redirect the damage and destroy Synaptic Interruption.
  • When using The Super Scientific Tachyon’s incapacitated ability that reads: “Move the bottom card of a deck to the top of that deck now,” you get to see what the card is.
  • Tachyon a Synaptic Interruption in play. She plays Lightspeed Barrage to deal damage to herself, then redirects it to another target so that Synaptic Interruption is destroyed. The Synaptic Interruption now in the trash counts towards the damage dealt by Lightspeed Barrage (effectively increasing it by 1).
  • The Crowd’s Favor card says “When a hero target destroys a non-hero target” (gain a token). If Tachyon uses Sucker Punch to destroy a target, the heroes get a token. Death Caller also counts.
  • Suppose “Wrong Time and Place” is out, and Tachyon is about to deal herself damage to keep Pushing the Limits. That damage can be redirected to Setback, or he can remove 2 tokens from his unlucky pool to redirect it. He is not allowed to redirect it back to Tachyon so she can keep Pushing the Limits. You’re EITHER redirecting to Setback OR redirecting from Target A to somewhere else - you cannot redirect from Target A to Target A, so you cannot redirect from Tachyon to Tachyon. Follow-up: If you have the tokens, you must redirect damage that would be dealt to Setback that meets these qualifications.
  • The Operative’s text is adjusted to say “When The Operative would be destroyed, her character card flips instead.” This clarifies that she behaves like Baron Blade, and Sucker Punch does not lead to shenanigans.
  • There is an exception to the order of operations ruling relating to reacting to damage being dealt. A card (or cards belonging to a hero/villain) that reacts to damage being dealt to it reacts before other cards do. The card dealing the damage and other interested cards happen afterwards and can be ordered by player choice.
    • Example: Suppose Mr. Fixer has Dual Crowbars and Bloody Knuckles in play. Omnitron has Adaptive Plating Subroutine but is not immune to anything yet. Mr. Fixer uses Strike to hit Omnitron for 3 melee damage. Omnitron's HP goes down by 3. Then, by this ruling, the text on Adaptive Plating Subroutine must react first and make Omnitron immune to melee damage. Then, the text on Dual Crowbars reacts and Mr. Fixer can deal damage to another target. Without this ruling, you could use Synaptic Interruption and careful ordering to hit Omnitron twice before it becomes immune to melee damage.

Spiff's SotM Rules and Clarifications

Hypersonic Assault

  • This card deals each non-hero target 1 sonic damage. Any target dealt damage this way cannot deal damage until the start of your next turn. Some cards deal damage in response to having been damaged (Ambuscade’s “Sonic Mines” for example), and because the two sentences on “Hypersonic Assault” are separated, it may seem like the order of operations would go like this – Tachyon deals damage, the target card deals its damage back, and then the second sentence kicks in saying that the targeted card can’t deal any damage (now that it’s too late). However, that second sentence is just meant to modify the damage being done by the first sentence and there isn’t any separation between the two operations. so the correct order would be - Tachyon deals damage, which causes any target damaged to not be able to deal their damage, then when the targeted card tries to deal its response damage, it can’t. Answers to Debated Questions

Lightspeed Barrage damage

  • This card reads, “Tachyon deals 1 target X melee damage, where X = the number of Burst cards in your Trash.” if she has 9 Burst cards in her trash and there is a +1 bonus to damage, she will deal the target 10 damage instead. She doesn’t receive the bonus damage for every card in her trash.

Super-Scientific Tachyon’s “Experiment” power

  • This alternate tachyon character card’s innate power says, “reveal the bottom two cards of a deck. if they share a keyword, put them into play. if not, discard them.” If Tachyon has just one card in her deck, you could still use this power, though it would just result in discarding that remaining card. remember, revealing cards does not force a reshuffle, so you would just reveal the last card in the deck, try to compare two revealed cards but be unable to do so because you only revealed one card, so since you couldn’t have found a match, you would just discard the card. Experimenting on a single-card deck Tachyon’s player gets to decide the order in which the two cards she reveals are played or discarded. Fireside Chats
