DEATH BATTLE: Red VS Peashooter

Angry Birds vs Plants vs. Zombies

Connections:

Both are mascots of games developed by small studios in 2009 (Rovio Entertainment and PopCap Games respectively) that have grown into well-known franchise

Both fight against green species (Pigs and Zombies respectively) to prevent them from stealing and eating what is dear to them (eggs and the Player's and Crazy Dave's brains respectively)

Both are usually the first characters you unlock in games of the franchise.

Both have different forms and versions like a 3D version where they have limbs (Angry Birds Movie Red and Garden Warfare Peashooter), fire forms (Fire Bird and Fire Peashooter respectively), space forms (Super Red and Cosmic Pea respectively) superhero versions (Red Rammer and Green Shadow respectively), versions from/associated with the previous era (Knight Red and Primal Peashooter respectively) and versions they got as a result of collaboration (Red was in the role of various characters from Star Wars and Transformers and Peashooter got the form of Berry shooter which is based on Aquafina flavosplash)

Additionally, the development studios of both games were bought by companies with controversial reputation (SEGA and Electronic Arts respectively)
