Tsunami is a colossal powerhouse, one of the largest Decepticons under Megatron's command. His power is backed up by a brain that does exactly run at optimal strength; he's not so much stupid as he is single-minded and easily frustrated, although his tendency to shout his own name repeatedly as a sort of battle cry doesn't do much to refute his reputation as a gentle giant. In battle he is merciless, an unyielding engine of destruction on his enemies.
