So, here's my moveset concept of Opa-Opa and Harrier as a dual character I already shared on a
Space Harrier thread, with the latter being a main character who the player controls with Opa-Opa as a CPU assist like Nana (for Popo) and Luma (for Rosalina), assisting Harrier in some of his attacks like options in shoot 'em up games. When Harrier is KO'd, Opa-Opa immediately exploes similarly to a latter (Luma) and Mega Man.
For their shields, Harrier and Opa-Opa uses a Bit shield (from the PS2 remake) and Shield (from Fantasy Zone II: The Tears of Opa-Opa/Super Fantasy Zone) respectively.
Neutral Attacks:
- Jab Combo: Harrier shoots a energy projectile from his cannon, while Opa-Opa shoots a small laser beam. Can be spammed by holding the button.
- Forward/Back Tilt: Harrier can move around while shooting with his laser cannon and even move backwards. Opa-Opa also shoots beams while moving. Same as Jab Combo, Mega Man's Side Tilt and Banjo's Breegull Blaster, but weaker.
- Up Tilt: Harrier swings his cannon upwards in an arc.
- Down Tilt: While crouching, Harrier slightly shoots directly in-front of him, causing a small explosion. Same as Samus's.
- Dash Attack: Harrier dashes forward with a headbutt by using his laser cannon. Opa-Opa twirls forward while dashing alongside Harrier.
Smash Attacks:
- Side Smash: Harrier shoots a ring projectile from one of the enemies, while Opa-Opa uses a weaker version of 7-Way Shot.
- Up Smash: Opa-Opa aims upwards and fires a Wide Beam above Harrier.
- Down Smash: Harrier shoots a powerful burst of flames upwards, while Opa-Opa launches two fire waves on each sides via Fire Bomb, surrounding them at both above and around their sides.
Air Attacks:
- Neutral Air: Same as Jab Combo. Harrier can slightly glide on the air like Peach, though it only applies here.
- Forward Air: Harrier swings his cannon vertically downwards in-front of him. Acts as a meteor-smash.
- Back Air: Harrier uses his cannon's boost to back-fire behind him, propeling forwards a bit.
- Up Air: Opa-Opa flies above Harrier and twirls upwards a bit.
- Down Air: Harrier shoots a powerful burst of fire directly below himself, while Opa-Opa shoots a 3-Way Shot (from Fantasy Zone II) downwards.
Grab/Throws:
- Grab/Pummel: While Harrier grabs an opponent with one hand, Opa-Opa slaps them with Big Wings by flying in-front of their face first.
- Forward Throw: Harrier drags an opponent across the ground a short distance as he flies with his cannon, before throwing them forward. Same as Ridley's Space Pirate Rush.
- Back Throw: Harrier throws an opponent backwards, and Opa-Opa then shoots a Laser Beam to send them flying away further.
- Up Throw: Harrier flies up high, before slamming an opponent down onto the ground. Works same as King K. Rool and Kirby's.
- Down Throw: Harrier slams the opponent on the ground with his cannon and Opa-Opa flies up, shooting a few small projectiles downwards in rapid succession to pin them down.
Special Moves:
- Neutral Special: Lock-On/Twin Bomb - Harrier aims his cannon forward and shoots a few laser beams, doing chip damage unlike his Jab Combo/Forward-Back Tilt/Neutral Air. Shots will miss if an opponent is outside the reticle even if they overlap them, though Opa-Opa tosses two small bombs forward to help Harrier, which explode on-contact. Based on how Harrier attacks in the PS2 remake and works same as Palutena's Autoreticle.
- Side Special: Komainu Rush/Rocket Engine - Harrier summons dog-like creatures called Komainus as they form a barrier in-front of him and he rushes forward. Opa-Opa also flies forward at high speeds by using a rocket engine on his back. Same as Banjo's Wonderwing, but not limited and has bigger endlag.
- Up Special: Flight/Turbo Engine - Harrier uses his laser cannon to fly freely around for a few seconds, able to shoot energy projectiles while doing so, even though he can't turn around. Opa-Opa follows him with a Turbo Engine.
- Down Special: Flash Bomb/Smart Bomb - Harrier summons a Flash Bomb (from the PS2 remake) and activates it, summoning a light-like explosion around him which stuns opponents within range. Opa-Opa also holds a missile-like Smart Bomb to give Harrier's explosion some damage, but only at the epicenter.
Final Smash/All-Star Move (in a clone thread):
- White Dragon/Heavy Bombardment: Uriah flies besides Harrier, who hops on him as he rides across the stage and sometimes does loops, while Opa-Opa flies into the middle of a stage and summons a few giant weight-like Heavy Bombs to fall onto opponents who manages to dodge Uriah. Works like a combination of Rayquaza's boss fight in Brawl and Ness & Lucas' PK Starstorm.
