I'm a huge fan of tokusatsu, and we only have Kamen Riders, Ultras, Kaijus and a few other characters, we need more variety. If I had to choose, it would be:
1. Kaiketsu Zubat
2. The three Uchuu Keiji, Gavan (a decente one), Sharivan and Shaider
3. Garo and Zero
4. Kikaider (a decente one) and Hakaider
5. Cybercops (the whole team)
