i have no idea what kind of love those 2 have for each other but it is strong and really the only strong love they have for another person (btw yes i am including romantic because no they are not actually canonically brothers, otherwise, i would not include romantic).
i cant be bothered to make their pfps so instead take a screenshot from the best bit from a snapcube real time sonic fandub.
(nvm at the moment wattpad isnt letting me put in images so pretend its that one bit that goes 'ive come to make an announcement: shadow the hedgehog's a b**** a** motherf****er')
