"This must be the secret of the Seventh Universe...the power of trust..."
Goku (who is struggling to transform from his base form to Super Saiyan) and Frieza - who have both gone well beyond their limits - utilize a powered up Nova Strike to ram into their opponent in order to create a massive explosion.
Usage and Power
Goku and Frieza utilized this attack in the final moments of the Tournament of Power in order to defeat Jiren. Frieza began the technique after asking Goku to throw him into Jiren and successfully hitting the latter with his Nova Strike, nearly eliminating Jiren, who only managed to save himself by spinning them into a dangerously low platform. Goku (who is struggling to maintain and even power up into his Super Saiyan form) flies in and tackles Jiren. Frieza follows Goku and when Goku finally powers up into a Super Saiyan, Frieza powers up as well and goes for another Nova Strike, this time with Goku performing the technique as well, eliminating Jiren and themselves.
