Ok so my headcanon is that Heatwave really likes making pet names for everyone, so he would call Boulder “B” for short or “BB” for “Boulder Babe” (or for more fluff: “Honey B”)

Boulder likes teasing and making Heatwave mad so he’ll always poke fun at Heatwave about tons of things, but Heatwave just kinda acts mad and talks back.

Heatwave in the show gets really uncomfortable around snakes because he finds them gross so when theres a snake in the bunker it’s basically the classic “Get-Rid-Of-That-Spider-Please-Its-FreakING-ME-OUT’ thing. Boulder just picks the snake up and takes it outside while Heatwave nopes out.

They act like they’re platonic in their jokes but its really obvious they’re flirting. To the point were Blades and Dani are kinda like ‘get a room please’.

When other people are around Heatwave acts like he’s not interested in science but when its just him and Boulder he’s like a kid in the candy store, going around picking up random things and pushing buttons while saying “What does this do?” and tries to help build things, but fails because he doesn’t understand half the stuff going on.

              - bonus: They make fake volcanoes on their free time.

Heatwave is rather shy when it comes to personal/intimate things, or rather, anything outside of their mission/job: to protect and learn about humans. Boulder is more confident and outgoing. Long story short, Boulder is the talker/leader of the duo in personal matters, while Heatwave is the quieter/follower of them.

Boulder’s show of affection is fluffy (snuggles, huggles, kissies), Heatwave.. his affection more NSFW...

Boulder frequently paints Heatwave’s face while the latter is recharging. With washable paint, of course.

Boulder also likes spooking Heatwave a lot. Like hiding for long periods of time then jumping out and startling him.
