Tigger has a cheerful and out-going disposition. He is very competitive (in a friendly way) and has COMPLETE confidence in himself. Although he can seem very arrogant, he has a heart of gold and is willing to do anything to help his friends. While friendly in terms of the Hundred Acre Wood's storyline, Tigger is often found bothersome at times, as he engages Sora in many puzzles and/or games that involve his love for bouncing.
Despite this, Tigger is shown to be rather illiterate, since he cannot verbally spell his name properly, shown when he says "guh" instead of "G" and "er" instead of "e-r".
