I think the strongest male জীবন্ত character is Ed from FMA,Yes আপনি can feel free to disagree,but I believe mentally he's extremely strong based on everything he's been through in life and he's pretty strong on the outside as well..minus his rather short appearance ;)
Envy from FMA, hands down. He's immortal, sexy, a shapeshifter, and he can completely pwn anyone in battle. Don't let his adorable appearance trick you! He's so strong, he makes Chuck Norris's head spin.
