My version of "Belmont":
The character uses a combination of martial arts and his whip, similar to how ZeroSuit Samus attacks.
The character is not fast, but rather slow and bulky, like Ike or Link.
Medium build.
Attacks (I actually thought this through so that they're not OverPowered):
Normal Attacks:
-Standard: Punch, Kick, WhipSlash Combo A (Similar to Ike's Combo, only with an side-swiping Whip attack at the end)
-Down Tilt: Low Kick (stolen from Maxim Kischine's Down+Attack)
-Up Tilt: "Hilt" Punch - Belmont attacks straight up with a small jump whilst holding the hilt of the whip, similar to Ike's Up+Attack
-Side Tilt: Short Slash - Belmont slashes with slight range, either with his whip, or with the Dagger Subweapon, (without throwing it).
-Running: Long Slash - Belmont stops running and does an overhead arching whip attack. Slightly more range than the Side Tilt.
Smash Attacks.
-Up: Belmont charges up two Axes in his hand, does a X-slash directly above him with them. Charging longer makes the axes fly slightly up instead of just in his hands.
-Side Smash: Double Slash. Belmont slashes with his whip in one arc, then does another stronger returning slash, similar to Link's Double Sword Slash Side Smash.
-Down Smash: Double Holy Water. Belmont throws vials of Holy Water right at his feet. Longer charge means longer distance traveled by the flames.
Grab:
-Extending Whip. Belmont does the classic whip animation as a grab. The range is similar to ZeroSuit Samus's and the attack takes about as long. If an opponent is caught, Belmont retracts the whip, and with it his opponent, setting them up for the grab.
-Hold: smacks the hilt of the whip against the opponent's face.
-Forward Throw: Smacks a HolyWater bottle against the opponent as they release them from the throw, setting them on fire briefly.
-Backwards Throw: Throws the opponent diagonally up + forward, throwing a dagger at them immediately afterwards. The effect
-Down Throw: Throws the opponent directly under him, does a KickDown on them. See any Down+Jump kick animation (SotN, HoD, AoS, DoS, PoR, OoE).
Specials:
All D-Specials use a generic animation to create an item projection.
-Standard: Daggers. Belmont sets up dagger throws. The attack is similar to Sheik's Needles. You can throw III at max.
-Side: Cross Boomerang. Stronger than Link's, but cannot be angled nearly as much. Very slight up or down variation control. Belmont's longest-ranged attack.
-Down: Burning Mode Projection. Briefly channels his inner power to heal from Energy Attacks (acts the same as Ness's PK Magnet). One of Sonia Belmont's powers, granted immunity originally. Graphically, it just projects a light-based clone of Belmont.
-Up: Uppercut Whip. Stolen from Richter Belmont.
Alternate Special 1
-Standard: Grant's daggers. Slower daggers that are more powerful.
-Side: Morris Boomerang. Crescent-shaped boomerang with more vertical control and speed, but less damage.
-Down: Rib Shield Projection. Acts as a reflector. Taken from Simon's Quest's "Rib of Vlad". Graphically, the projection looks like a shield with a rib encrusted in it. Although it projects only in front of Belmont, there is a ring of light engulfing Belmont that reflects projectiles from all sides. The ring of light resembles a small version of Gardevoir's attack (see Gardevoir Assist Trophy)
-Up: Super Jump (Griffin's Wing - Harmony of Dissonance). Large vertical range jump, allows Belmont to attack after the ascension.
Alternate Special 2
-Standard: Long Daggers. Fast lance-like long daggers. Can only throw one set of three that angle slightly up, center, and down. Take longer to charge. Strong & fast, but cannot throw multiples since all three are thrown at once. These are Richter Belmont's daggers.
-Side: "Check" Boomerang. Faster boomerang than the Cross Boomerang, slower than the Morris Boomerang, does not come back. Checkmark-shaped. From Haunted Castle.
-Down: Invisibility Combo. Uses an Invincibility Jar as a Counter, Stuns a connecting attack with a StopWatch. Avoids attacks using the Invisibility Jar item. Works like a Counter move. For reference, see Lucario's "Stunning Double Team"'s description "A counter move that can paralyze your opponent if timed correctly". The jar looks like a classic CV1 jar, only with updated graphics. When the jar breaks in front of Belmont, it releases the magic that allows Belmont to 'phase' from the attack using invisibility, at which point, Belmont attacks the opponent from its backside using the PocketWatch to hurt them and stun them.
-Up: Roc Wing. Longest recovery move, slowest recovery move. Ample vertical movement. CANNOT attack afterwards. Does not deal damage. Taken from Nathan Graves's SuperJump item move.
Final Smash: Grand Cross
Belmont uses the power of the Cross as an ItemCrash, creating a large white pillar of light around him, with arms of light extending out to create a cross of light. Taken directly from Julius Belmont's Castle-destroying attack from Aria of Sorrow. Opponents nearby can get sucked in for damage, like in Aria of Sorrow.
I agree with GuyStarwind about using Alucard as an assist trophy, with similar moves.
