Keitai Denjuu Telefang 2 - Speed

Keitai Denjuu Telefang 2: Speed is a Japanese-style RPG where players are T-Fangers who collect Denjuu (mobile phone beasts) using a D-Shot device. The blue-haired protagonist Kyō teams up with friend Midori to find his missing father, battling evil Denjuu like Diablos who threatens the antenna trees connecting worlds. Battles feature up to three Denjuu per team with habitat-type-based weaknesses (Mountain, Sky, Forest, Aquatic, Desert, Grassland) and attack types. The Speed version emphasizes faster battles and includes version-exclusive creatures. It stands out for its phone-call collection system, reversible evolution, and action-in-battle elements, with single-player exploration and random encounters.
