Partner Viability Tool
Is Pikachu good in Pokemon Yellow?
Yes for story and mid-game Electric work—with clear limits. Partner Pikachu is free, follows you, learns Thunderbolt at level 26, and never needs a trade. It is also frail, stone-locked (no Raichu), and loses late to Jolteon or Zapdos. Use the phase grades, matchup table, and keep/bench checklist below.
Fast Answer
Keep it—then upgrade if you want
For a normal Yellow playthrough, keep partner Pikachu at least until Thunderbolt (26) and the Cerulean Bulbasaur happiness check. After Celadon you can evolve Eevee into Jolteon, and after the Power Plant you can catch Zapdos. Pikachu remains a valid full-run mon if you like the anime partner; it is just not the strongest final Electric by base stats.
Verdict board
What “good” means here
Where Pikachu shines
- Always available from minute one
- Level-up Thunderbolt (Yellow partner set)
- Strong vs Water / Flying story fights
- Happiness gates Bulbasaur gift
- Follow sprite + partner flavor
- No trade required ever
Where it struggles
- 35 HP / 30 Defense—paper bulk
- Special 50 is only okay mid-game
- 0× Electric into Ground (Brock, Dig, Giovanni rocks)
- Partner refuses Thunder Stone → no Raichu
- Jolteon / Zapdos outscale late
- PP pressure if Thunderbolt is the only real STAB
Phase grades
How good is Pikachu over the run?
Early · Brock–Misty
Useful, not solo carry
Thundershock handles early Water and Flyers. Sit out Brock (Ground immunity). Quick Attack at 11 helps revenge. Bring Mankey / Nidoran / Butterfree for Pewter.
- Key levels: 8 Wave · 11 Quick Attack · 15 Double Team
- Deep guide: Beat Brock
Mid · Surge–Silph
Peak partner window
Thunderbolt at 26 makes Pikachu a real mid-game nuke. Excellent for water routes, many Rockets, and general Flying coverage. Still fold to Ground and heavy physical hits.
- Optional TM24 after Surge for an earlier bolt if you lag levels
- Keep happiness ≥147 for Bulbasaur
Late · Gyms 6–E4
Serviceable, not optimal
Speed stays respectable; bulk and Special trail modern threats. Giovanni’s Ground core hard-walls Electric. League still has Water and Flying answers, but Jolteon/Zapdos do the same job safer.
- Pair with Ground-immune or Ground-proof teammates
- See Elite Four guide

Recommended story moveset
TM pool highlights from the Yellow base data: Thunderbolt, Thunder, Body Slam, Seismic Toss, Swift, Thunder Wave, Flash, and more—no Surf/Fly/Strength on standard TM/HM list for Pikachu (Surfing Pikachu is a special case).
Moveset tips
- Replace Thundershock the moment Thunderbolt lands
- Thunder’s 70% accuracy is risky vs gyms—bolt first
- Seismic Toss (TM) stabilizes damage vs bulky Water
- Light Screen helps special tanks but costs a damage slot
- Never lead into known Ground STAB

| Brock | Bench | Rock/Ground · Electric does 0× | Open | |
| Misty | Primary answer | Water weak to Electric; Starmie still fast | Open | |
| Lt. Surge | Mirror / support | Raichu resists Electric; use Ground if you have it | Open | |
| Erika | Situational | Grass resists Electric; bring Fire/Flying/Ice | Open | |
| Koga | Support | Not ideal into Poison; Wave can help speed control | Open | |
| Sabrina | Chip only | Psychic outspeeds/out-specials; use your own Psychic | Open | |
| Blaine | Neutral | Fire not weak to Electric; Water/Rock better | Open | |
| Giovanni | Bench most of it | Heavy Ground core walls Electric | Open |

Play tips
Get more value from partner Pikachu
Don’t force Brock
Switch to Fighting / Special answers. Forcing Thunder Shock is the #1 “Pikachu is bad” myth generator.
Race level 26
Thunderbolt transforms the mon. Train on Routes 24–25 and water routes once you have a safe plan.
Happiness is a real stat
Bulbasaur wants 147+. Walking, levels, and heals help; long PC time and fainting hurt. Mechanics Lab models it.
Electric is not a solo type
Pair with Ground, Water, or Ice coverage so Giovanni and Ground wilds never soft-lock the party.
FAQ
Pikachu viability questions
Is Pikachu good in Pokemon Yellow?
Yes for story and mid-game. Free access, Thunderbolt by 26, and Water/Flying coverage. Late game prefers Jolteon or Zapdos if you optimize, but a full-run partner clear is completely fine.
When does it learn Thunderbolt?
Level 26 on the Yellow partner learnset. TM24 Thunderbolt from Lt. Surge is also an option if levels lag.
Should I keep Pikachu forever?
Keep through happiness gifts and mid-game. Bench only when a stronger Electric (or the party slot) clearly improves your clear—never release the partner if you still care about follow sprite / completeness.
Is Jolteon better?
As a pure late Electric attacker, yes (130 Spe / 110 Spc). It arrives later via Celadon Eevee + Thunder Stone.
Can the partner become Raichu?
Not via Thunder Stone on a normal cart. Details and rare workarounds: Does Pikachu evolve?
