She is based on the banana, an edible fruit, botanically a berry, produced by several kinds of large herbaceous, flowering plants in the genus Musa; and the Tyrannosaurus, more commonly known as the species Tyrannosaurus rex, a genus of coelurosaurian theropod dinosaur.
Her name is a portmanteau of "banana" the real-life plant she is based on; and "Tyrannosaurus rex" the real-life dinosaur she is based on.

Strategies
With
While initially not the most cost-effective plant, Bananasaurus Rex can become very strong in the late game. However, since her base stats aren't that great, Bananasaurus Rex needs to get some stat boosts to truly shine.
Aside from pure stat-boosting cards, you can also increase her stats by drawing cards, examples being Flourish and Holo-Flora. While all other classes have ways to draw cards as well, Green Shadow is arguably the best hero in terms of card draw due to her abundance of card-drawers like Sow Magic Beans, Planet of the Grapes, and Lima-Pleurodon.
Bananasaurus Rex also acts as an alternative to Template:PvZHLink, but she does not benefit from Template:PvZHLink. However, Team-Up plants like Torchwood can protect her in the early turns, because she is weaker at the beginning of the game.
Party Thyme is a very good choice too, since Bananasaurus Rex does a bonus attack after she has finished attacking in the Fight! phase, causing it to draw cards to boost Bananasaurus Rex. However, it is weak, so make sure to protect and/or boost Party Thyme. Other cards that draw or Conjure cards, like Sage Sage and Bean Counter, can also boost her. Mayflower giving the player a card upon hitting the zombie hero can also boost Bananasaurus Rex's stats. Keeping a received superpower works too because it counts as drawing a card.
Flourish, Re-Peat Moss, Bananasaurus Rex, and possibly Party Thyme together are a great combo. When you play Flourish, Bananasaurus Rex will gain +2/+2 while Re-Peat Moss does a bonus attack. With Party Thyme as well, you will draw another card, boosting Bananasaurus Rex's stats by +1/+1 again.
Against
You should target this plant before she becomes too strong. This can occasionally be very hard to do if lots of cards are drawn. However, the turn she is played can be troublesome to deal with if not boosted. This is because most tricks cannot deal with this efficiently, and will need support. In addition, brains will likely be spent, and there will be no time for tricks. Knockout and Electrobolt can easily destroy this before anything happens. The Smash could also use Slammin' Smackdown as well. If she gets out of control, use instant-kill cards like Rocket Science, Locust Swarm, Deadly zombies, or Template:PvZHLink to destroy her. If none of these options are available, destroy plants that give the opposing hero more cards such as Mayflower or Party Thyme to slow down the process of boosting the Bananasaurus Rex. Unless necessary (such as deliberately boosting her before playing Rocket Science), do not use Regifting Zombie or she will gain +2/+2.
