Firstly, I don't fight people at all - but it doesn't mean I couldn't lol! 😄 Up until I became a Christian three years ago, I trained for a fair while in Seven Star Praying Mantis, Wing Chun and a little tiny bit of Tai Chi (don't laugh - even tai chi can do the business lol!).
But against Robin...? The Boy Wonder...? Depends a lot on the incarnation.
Robin from the TV series...? Without a sweat! 😄
From eighties New Teen Titans...? Dunno - he was very intermittent if you know what I mean. Generally he'd kick my ass, but every now and then he'd make a poor showing that'd make me say 'I could do better!' lol! 😄
When he became Nightwing, he became a lot tougher and he'd kick me to a bloody pulp everytime.
Modern day Teen Titans, he's too fast and skilled by far - I probably wouldn't be able to hit him lol.
Overall, Robin's just a slightly watered down, more family friendly Batman. He still has serious moves and against his better incarnations, I doubt anyone short of a world class martial artist could give him bother.
I'm not that man! 🙂
And I'd seriously doubt anyone here is, lol! 😄
