Suggested by Sonic Alex Rider is a pretty decent agent. He has quite a lot of gadgets at his disposal and as the books went on he did get proper training in hand to hand combat. Still, there’s a big difference between ordinary training and being trained by Batman. Robin’s gadgets are better and he’s also the superior fighter so that leaves Alex Rider out of luck right off the bat. There’s just not a whole lot that he can really do against Robin here. For Robin it would just be like taking down another minion. Robin (Tim) wins.
