Gramps

Gramps, also known as Old Man StreetPass, is a character that appears in. He is an elderly citizen in charge of the game's StreetPass functionality, Shadow Link Battles, and stands in the StreetPass Meadow on the western side of Kakariko Village.

Despite his unassuming appearance, Gramps also serves a less-obvious role as a secret boss. Once all 50 Challenge Medals have been collected, Gramps can be challenged to a duel in similar fashion to fighting a Shadow Link. He is the strongest opponent in the game, wielding upgraded versions of all the items and gear available to Link.

Biography
Upon first speaking to Gramps, he will explain how StreetPass works and help the player create their Shadow Link. Once a Shadow Link has been created for the first time, Gramps will plant the StreetPass Tree just west of Link's House. The apples on the tree will increase with the number of challenges that are completed. Gramps can be spoken to at any time to make changes to the Shadow Link's inventory, look at the list of Challenges and earned Medals, or have him repeat an explanation of how StreetPass works. Occasionally when speaking to him, Gramps will ask the player if they have visited the Apple Tree. If the player says that they haven't, Gramps will wonder aloud that the player must prefer oranges to apples.

Speaking to Gramps after obtaining all 50 Challenge Medals prompts him to challenge the player to a duel. Defeating him rewards the player with 5 rupees, and allows the player to rematch him at any time. Gramps explains that his bounty is so low because he pays for all the Shadow Link bounties out of his own pocket, and reveals that he established the Shadow Link Battles so that he could meet someone who is stronger than him.

Gramps is also shown during the credits sequence, following scenes of the sages returning home and the Hyruleans celebrating. Unlike the other characters, Gramps is not seen to be celebrating, but simply standing in the StreetPass Meadow.

In battle
Going by the player name of "Legendary", Gramps is the strongest boss in the game. He has 20 hearts, all 50 Challenge Medals and fully upgraded gear; the Master Sword Lv3, Hylian Shield, Red Mail (although it is not visible on him), Pegasus Boots, Stamina Scroll and the Bee Badge. He will use two of any item in its upgraded quality and may also use Blue, Yellow or Purple potions. In addition, Gramps also knows the Great Spin.

The battle against Gramps will take place in a randomly selected arena, however the Desert Arena is usually only chosen if he has equipped the Sand Rod. He is extremely agile, and will frequently dodge the player's attacks or defend himself with his shield.

Characteristics and Weaknesses
The battle will differ somewhat depending on the arena, and the items that Gramps brings to the fight. The Purple Potion can be particularly devastating to the player if Gramps is given the opportunity to use it. It will deal up to 8 hearts of damage, except in Hero Mode where it can instantly deal up to a massive 32 hearts of damage. It's not recommended to bring Bees, which are completely ineffective on Gramps as he carries the Bee Badge. It's best to circle around Gramps and continually stun him with the Boomerang, opening a chance to safely attack him and preventing him from using his items.
