Here is how I think Wasp could work in Marvel Rivals. I made a concept for her a while ago but I’ve changed some things. 

Class Strategist

She can fly

Primary
Wasps primary attack would be blasters on her wrists that can heal and do damage. It would be a similar rate of fire to Peni Parker. 

Ability 1: Bio-Electric Stingers
Wasp can shoot stingers that will apply different effects depending on if she shoots her teammates or enemies. 

If she shoots her teammates it will apply healing over time and a damage boost. 

If she shoots her enemies it will deal damage and apply anti heal. 

Wasp can have up to two at a time. 

Ability 2: Gauntlet Enhancements 
Wasp can temporarily double the rate of fire for her primary ability allowing double the damage and healing for a short time. It will last about 5 seconds. During her ult this ability will triple the rate of fire instead of doubling it.

Ability 3: Shrink/Grow
Wasp can shrink which will give her a big speed boost. When she is small she does less healing and damage but she can still use her abilities. Every time she shrinks or grows the ability goes to cooldown for 7 seconds so it must be used strategically.

Ultimate: Size Manipulation 
Wasp can choose to either grow her team and shrink her enemies or shrink her team and grow her enemies. This will only apply to the area around her. Wasps gauntlets rate of fire will be doubled the entire ult. Wasp can also still use her abilities. Using Gauntlet Enhancements will now triple the rate of fire instead of just doubling it. 

If Wasp chooses to grow her team and shrink her enemies it will apply these effects. 

Teammates will grow to the size of Groot (even bigger for vanguards). They will gain a huge damage boost and lots of over shield.

Enemies will shrink to the size of Jeffs fin. They will gain weakness which will make their attacks do way less damage.

If wasp chooses the other option and shrinks her team and grows her enemies, then these effects will apply. 

Teammates will gain a large speed boost and healing over time. They will shrink to the size of Jeff’s fin.

Enemies will grow to the size of Groot (bigger for vanguards) and slowness will be applied. They will also gain anti heal.

This ult lasts for about 8 seconds before everyone returns to original size. Wasp will shrink or grow with her team if she does the ult. Using the Shrink/Grow ability will return her to normal size no matter what she chose for her ult. She will still keep the effects of the ult even when regularly sized  for as long as the ult lasts. The area of effect for this ult would be the size of Invisible Woman’s ult. Every one in this area will either shrink or grow depending on what was chosen by Wasp.

I’d appreciate any feedback.
