Ok, so a couple years ago (5-6 years), a friend of mine had a toy which resembled a young boy with spicky red hair and a big, red robotic glove. It was from a manga or an anime. Who was he?
This seems like the child or teen version of Hellboy as seen in Hellboy 2: The Golden Army. He had biggish horns (which he ground in adulthood, "to fit in") that might have been mistaken for spikey hair (though his own hair was black, the horns shaded from black to red when long), and his right hand is huge and stony and might easily be mistaken for a robotic glove. Hi skin is red all over, but he often wears (as an adult) an overcoat in a yellowish color.
