Experiment n° 001:
Moira splices Wrecking-ball genes with Junkrat genes.
Result:
Hamster with a rip tire mecha, with double grenade launchers. Has grappling hook but can also climb walls. Has adaptative shields. Ultimate is like mine-field but with traps.
Create your own splice next.
Inb4 not reallistic because mecha has no genes (I know, its all fun)
Experiment n° 002:
Moira splices Reinhardt genes with D.va genes.
Result:
A tiny little Korean gamer girl that when approached will yell in German and charge into you at 500 miles an hour
Poor thing won’t be able to buy booze because underage, unless she gets a fake id.
Number which ever we are on
Moria splices doomfist and mercy to make the almighty moomfist .
A mercy sized doomfist with a halo and staff and floats around healing and punching everybody simultaneously
004: Boop² (Sombra + Lucio)
This creature hacks people’s audio feeds to make them listen to loud music. Its ultimate creates and destroys shields at the same time.
If moomfist punches an ally into a wall they get healed to 100% hp?
Perfect you just came up with his third passive 
Loud Mariachi music, I hope.
Probably EDM remixes of mariachi music.
Experiment n°number
Roadhog and Sombra:
A monstrosity than can turn invisible and then pop out of nowhere to one shot you! When it hooks you, you instantly get hacked!
This hero is luck based where it either spawns as a really fat Sombra or a really skinny Roadhog ( big hitbox with small health or small hitbox with lots of health)
Roadhog and Tracer
A fat annoying british woman who zips around the place, hooks you through time and kills you with a bomb.
I can’t see how you could possibly find that annoying!
Can you seriously not find a fat british woman doing THIS annoying?
I’d love for a fat British woman to zip up to me to hook me through time and then kill me with a bomb!
You have a weird fetish
Ahh yes! the fat British woman hooking you through time and killing you with a bomb fetish
And to top it all, even though you would expect her to have a deep voice like Road, she actually has an even shrillier voice than Tracer’s.
The ground shakes as you see a giant figure waddle up from behind you, casting a giant sinister shadow over your body.
They lift a jagged scrap-metal hook into the air then Hiya! Tracer here!
Experiment n° 007:
Symmetra genes spliced with Torbjorn genes.
Result: Torbetra
A very short but curvacious indian woman with beard and moustache that can place up to three baby torb turrets which then move on their own, has a hardlight shotgun, and when ulting shoots puddles of liquid light, that provide allies that step on then with shields, and slows enemies.
She has 24 children.
Experiment n° 008:
Baptiste genes mixed with Ana’s, at a 1:2 ratio.
Result: Banana.
Armed with a modified version of Baptiste’s gun, Banana’s primary fire mode fires sleep darts in burts of three, with a secondary mode that belches out Ana’s bio-grenade instead of Baptiste’s heal-only version. When approached, she can charge her exo-boots and jump to the moon, and continue firing from there by using her scope. Nano Boost now makes its target immortal for the duration. If Banana dies, she can eaten to gain a respectable amount of potassium, vitamins B6 and C.
