Much like his counterpart, this version of Spike has always been by Stardust’s side since pretty much day one. He accompanies her on every mission and provides quick and able support with his ability to summon items on the fly from the Canterlot armory via scrolls. Also like his counterpart they share a strong connection together, much like that of a sibling bond. He looks up to Stardust, greatly admiring her ferocity and cunning nature, and Stardust similarly admiring his tenacity and resourcefulness.
He is not aware of the circumstances of how exactly he came to be in Stardusts care, and being partly to blame for that circumstance, Stardust has always viewed his upbringing as being one of her utmost priorities in life. It is because of this that she originally wanted him to have nothing to do with her career (despite his begging,) but eventually gave in when she began to see how capable he was.
Soooo yeah. That’s this universes Spike for ya. Usually this is the part where I ask you guys to suggest names but like I said beforehand, ‘Spike’ would fit this version him just fine so someone would need to suggest something REALLY good for me to reconsider. Until then he will simply be Spike.
EDIT: OKAY, so, while I haven’t really heard any names I want to use, I have heard one suggestion, and just so that there’s something to distinguish this spike from canon spike, this spike will officially be known as “Spyke.”
