Don't forget that PvZ 3 should have references to time travel and the multiverse

Lately I've been playing PvZ Heroes a lot more because of the update, so much so that, because of this, I always remember how much I like certain parts of all the Plants and Zombies games and that I'd like to see them again... it might just be a fan thing, but I think about it a lot because PvZ3 is a continuation of the franchise, which seems to be distancing itself from that. 

So, I don't know... it could be a separate mode with rescue missions or side quests given by Penny, who knows? I like how the Epic Realms in PvZ2C work as something extra, so you guys could kind of take inspiration from something like that.

Here are some ideas 👇

Dragons

Spits wind in a short-range area three lanes wide, dealing damage to any zombies within that area. Dragons spits out wind blasts to deal area damage to zombies at mid-range every 15 attacks. 

• 🍃📜Plant inspiration: Whirlwind Dragonfruit 
• 🏕️📜 Lawn inspiration: Pirate Seas
• 🍁📜 Threats: Broken tiles
• 🧬📜 Special Ability: Dragonflight! Flying over broken tiles. 

Witches and Sorceresses

Use magical sorcery to transform zombies into a random elemental plant or weakening zombies that are too strong to be transformed. 

• 🍃📜 Plant inspiration: Witch Hazel 
• 🏕️📜 Lawn inspiration: Dark Ages
• 🍁📜 Threats: Spells
• 🧬📜 Special Ability: Magic Mirrors. Immune to magic spells and can reflect them.

Dinosaurs

Dino-Plants can bite zombies in a nearby 2x3 area, devouring them when their health drops below 20%. They are able to slow down the zombies by roaring at them.

• 🍃📜 Plant inspiration: Veloci-Radish
• 🏕️📜 Lawn Inspiration: Jurassic Marsh
• 🍁📜 Threats: Dinosaurs
• 🧬📜 Special Ability: Dino-Roar. Dino-roar is especially frightening for other dinossaurs.

Aliens

Light up an area to let you see through fog, and give Lumos power to plants. The Lumos Power provides a temporary power boost to plants of the same type when fully charged.

• 🍃📜 Plant inspiration: Cosmoss
• 🏕️📜 Plant Inspiration: Far Future
• 🍁📜 Threats: Electric Fog
• 🧬📜 Special Ability: Purification. Dispels any negative effects.
