I think Sparkling Heatwave would be protective of the others (Chase, Boulder & Blades) if someone tries anything to either them or the Burns family.
(Tag on an old bean Blades post by @moroccos-apprentice.):
(Note: They're also the one who made David, the Morbot sparkling.)
Not shown: The Apprentice and two Burns sprinting to stop the incoming mauling.
Heatwave, despite being a bitty who’s likely to cause a fuss for not being given a snack, somehow still retained the feeling of being responsible for everyone’s safety the most.
Much as that’s true, he wouldn’t have the best judgment concerning what’s danger and having the appropriate response to it (for example, one time Kade had Cody in a headlock (because sibling shenanigans), Heatwave went berserk on Kade’s boots (while he’s still wearing it).)
