His grandfather is a "Mescalero Apache chief". Every nation has a chief (or most have); but the similarity of the phrase with the Super Friends character is undoubtedly deliberate.

And with his surname, it's obvious he'll gain size alteration powers somewhere down the line. Like Jae said. The only thing we don't know yet is whether his superhero name will be Longshadow or Apache Chief.
