The special attack is not that strong
Son Goku Super Saiyan Yard Rat is set as a special character, but since it deals +30% damage, it is not that strong.
Son Goku Yard Rat can also be strengthened with Legends Road Character
As the characters of Legends Road have been enriched,REDIt is possible to strengthen Z ability not only by Saiyan but also by Legends Road Tag. Consider the case where there is not much handheld because the rise value is high.
