"
T.G.", short for "
Tech Genus" (TG(テックジーナス)
Tekkujīnasu) is an
archetype used by
Antinomy in
Yu-Gi-Oh! 5D's. They are all
bionic in appearance to reference the identity of their user. They made their debut in
Extreme Victory. In the Japanese anime, each of them has a code in their name which references their
Type, followed by a number. This includes their status as they have X's at the end of their names to indicate their evolution of Synchro Monsters:
They are high tech
monsters from the future and they share a variation of this
effect in the
anime:
This card can also be treated as a Machine-Type monster. When a Spell or Trap Card you control targets this card, you can halve this card's original ATK and DEF. When this card is destroyed, you can add 1 "T.G." monster card from your Deck to your hand. You cannot Summon it this turn.
In
Yu-Gi-Oh! 5D's Tag Force 5, it is possible to use the card obtained during the same turn, and the
ATK and
DEF reduction is not present among their effects.
The real life version of the "T.G." cards consist of monsters who can "replace" themselves with different monsters when they're destroyed. Most of the non-Synchro Monsters search for other "T.G." monsters besides ones that share their name (for example, a "
T.G. Warwolf" can search for any "T.G." monster besides "T.G. Warwolf"), while all of the Synchro Monsters (except "
T.G. Blade Blaster")
draw cards or Summon monsters.
Despite their bionic appearance and names, the only existing
Machine "T.G." monsters are
Accel Synchro Monsters. All "T.G." supporting Spell and Trap Cards have an initialism in their names.
